    Looks like there might be a per game controller (and any other retroarch) option soon.

    Actually with any retroarch emulators, you can already have 1 retroarch file per rom/game and so you can change buttons, ratio or anything you want per game, but I only managed to make it worked with the old way to launch the emulators with es_systems.cfg (not using “_SYS_”).

    Here is my solution:

    1) You need to create 1 config file per rom using this type of name “” (for example and put them into your roms folder (they have to be in the same folder as your roms)

    2) You need to edit your es_systems.cfg by adding one flag into the line that launches your emulator (only emulators using retroarch of course).
    Here is the flag:
    –appendconfig %ROM%.cfg

    A real example:
    /opt/retropie/supplementary/runcommand/ 4 “/opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-fba/ –config /opt/retropie/configs/all/retroarch.cfg –appendconfig /opt/retropie/configs/EmulatorName/retroarch.cfg –appendconfig %ROM%.cfg %ROM%” “lr-fba”

    It works on my rpi2!

    By the way, anyone would know how to add an “–appendconfig” argument into the new _SYS_ command? I tried different formulations, but none of them workded.
    I guess we could slightly modify the file to add a 5th argument in the launch command. In the end we would have something like this:
    /opt/retropie/supplementary/runcommand/ 4 _SYS_ fba %ROM% /The/Path/I/Want/
